Description

  The present invention relates to a small wind power generator, and in order to enable the small wind power generator to be easily installed on a rooftop, a roof, or the like of a building, it depends on the wind pressure of a support column that supports the wind turbine part of the wind power generator. The present invention relates to a wind turbine generator and a method for installing the wind turbine generator, in which a support frame that facilitates reduction of oscillation and load / stress distribution is used.

  Wind power generation is attracting attention from energy and environmental issues, and is expected not only for propeller-type large-scale wind power generation devices but also for small-scale wind power generation devices as a means of distributed power generation in the vicinity of power consumption areas similar to solar power generation. It is growing. In general, it is easier to obtain strong winds that are preferable for wind power generation when the height of the wind is higher from the ground. In order to meet the expectations of small wind power generators as a means of distributed power, It seems indispensable to make it popular by installing it on the rooftop. However, conventional propeller systems are difficult to install on the rooftops of buildings in residential environments due to problems such as noise caused by wind noise from blades and scattering of damage. . For this reason, as a current method of supporting a small wind power generator, there is a tendency to make the support column as high as possible so as to obtain a preferable wind, but an elongated cylindrical member is used because of the influence of the cost and the like, as shown in FIG. In this way, a method of standing upright from the middle part with a slender member or a retentive material such as a wire is often used, but the column part is greatly oscillated by wind pressure and may be damaged or collapsed. Installation on a certain roof is difficult, and it is considered to be an unsuitable method for installation on the rooftop or roof of a building. In addition to this method, as shown in FIG. 11, a method is also used in which the cylindrical member of the support column is enlarged to be self-supporting and the foundation is enlarged, but this method increases the load on the building. In addition, there is a problem that it is difficult to apply to a sloped roof. On the other hand, low-noise wind power generators are appearing as a result of technological development, and the possibility that small wind power generators can be installed on the rooftops of buildings is increasing. For this reason, in order to promote the use of small wind power generators as a means of distributed power generation, it is possible to easily reduce the possibility of rocking, breakage and collapse due to wind pressure of the column of the wind power generator, and to the building to be installed. It is desired to propose a small wind power generator that can reduce the load and can be easily installed on the rooftop or roof of a building.

There are no prior patent documents directly related to this. As a slightly different support method, the present inventor has already filed “wind power generator (Japanese Patent Application No. 2004-202571)”.
